Paper Abstract

The availability of microcomputer control has allowed a new design philosophy to be introduced which is of particular interest for remote or unattended instrumentation. Instead of attempting to create systems that will retain their attributes (e.g., mechanical dimensions) in the presence of all perturbations, it is now possible to use an arrangement in which errors are expected, but reduced to tolerable values by the exercise of machine intelligence. This involves sensors to monitor performance and effectors that actively reduce the error. With such a concept it is frequently possible to achieve better results with lighter and more compact hardware and to eliminate the need for human intervention to retain calibration. The presence of a microcomputer also makes it possible for a machine to perform functions that were previously left to human judgement. One of these, the resolution of seeming ambiguities, is the subject of this paper.
